# Driftly: White Noise & Sleep

Driftly plays steady sounds, including white, pink, and brown noise, rain, and a fan, including while offline and without ads. Evidence that this kind of noise improves sleep is mixed. Driftly is not a treatment for insomnia, tinnitus, or any other condition.

Who it's for: People who want a simple sound machine on their phone to mask sudden noise while they rest or concentrate, including somewhere without a network connection.

## What it does

### White, pink, and brown noise

Three broadband sounds. White is a bright hiss, pink is smoother, and brown emphasizes the low end. None of them is a proven sleep treatment.

### Mixes, including rain and fan

Layer sounds, such as rain with a fan, and leave them playing.

### A sleep timer

Set the audio to stop after a period you choose, instead of running with no end.

### Offline, without ads

Sounds play from the iPhone. Driftly does not show ads and does not require an account.

## How it compares

A fan, a hardware sound machine, or an audio file you already own can do the same job. Driftly keeps several noises and a timer on the phone and plays them without a connection or an ad. Systematic reviews of broadband noise for sleep rate the evidence as weak and inconsistent. Use it as masking sound if you like it. Do not use it as medical care. If you are asking about tinnitus, talk to an audiologist.

## Questions

### Will Driftly help me sleep?

Maybe as a mask for sudden noises, and maybe not. Research on white and pink noise for sleep is mixed and the evidence is weak. It does not treat insomnia.

### Does it treat tinnitus?

No. If ringing in your ears bothers you, see an audiologist. A noise app is not care for tinnitus.

### Can I use it without a signal?

Yes. The sounds are on the device, and the app does not show ads.

### How loud should it be?

Loud enough to mask the noise that bothers you, and no louder. If you play sound near a baby, keep the volume low and the phone well away from the child. A 2014 Pediatrics study found infant sound machines at maximum volume were far too loud at 30 centimeters.
